WANTCOLUMNSANCHORED is desupported

Use UNMOVABLECOLUMNS to specify that table columns cannot be moved around by the user.

Before version 2.00, the WANTCOLUMNSANCHORED attribute was undocumented but still supported by the language, to simplify migration from 1.20.

Starting with version 2.00, the WANTCOLUMNSANCHORED attribute is desupported; you must use UNMOVABLECOLUMNS to specify that table columns cannot be moved around by the user.
